Introduction

Your waitlist form is often the first interaction users have with your brand. Here's how to customize it.

Dashboard Settings

In your form settings, you can customize:

  • Form Name: Display title on the form
  • Description: Subtitle text below the title
  • Email Label: Label for the email field
  • Button Label: Submit button text (e.g., "Join Waitlist")
  • Success Message: Shown after successful signup
  • Redirect URL: Optional redirect after signup

Field Options

Toggle which fields to collect:

  • Email (always required)
  • Name (optional)
  • Country (auto-detected from IP)

Share URL (Slug)

Create a memorable share URL:

joiner.page/your-product
joiner.page/beta-access
joiner.page/early-birds

Requirements:

  • Minimum 3 characters
  • Lowercase letters, numbers, hyphens only
  • Must be unique

Form Styling

Forms come with a clean, modern design that works on any site. The form automatically:

  • Uses Inter font family
  • Has smooth animations
  • Shows loading states
  • Displays success confirmation
  • Is fully responsive

Coming Soon

We're working on more customization options:

  • Custom primary colors
  • Dark mode support
  • Custom fonts
  • CSS overrides

Tips

Container Width: For best results, place the form in a container 400-600px wide. Background: The form has a white background with subtle shadow. Works best on light gray or colored backgrounds. Mobile: Forms are fully responsive and touch-friendly.
